Question
If water is leaking from a certain tank at a constant rate of 1,200 milliliters per hour, how many seconds does it take for 1 milliliter of water to leak from the tank?
- \frac{1}{3}
- \frac{1}{2}
- 2
- 3
- 20

Solution
Step 1
We first name the constant leakage rate r.
r = 1200 \text{ milliliters per hour}
Step 2
We then find the time in hours to leak one milliliter by dividing one milliliter by r.
t = \frac{1 \text{ milliliter}}{r}
Step 3
We then convert the time from hours to seconds by using that one hour equals 3600 seconds.
t = \frac{1}{1200} \text{ hours per milliliter} t = \frac{1}{1200} \times 3600 \text{ seconds per milliliter} t = 3 \text{ seconds per milliliter}
Answer
3 seconds
